SPRAYING MANIFOLD.

Application filed Marchli', 1923. Serial No. 625,732.

T all whom it may concern:

Be it known that I, PATRICK HENRY DAVIS, aci tizen of the United States, r esiding at Leonia, New Jersey, have 1nvented new and useful Improvements in fip-raying Manifolds, of which the following s a specification.

This invention relates to improvements in spraying manifolds, and more particua larly to such manifolds as are used 1n d1sh-' washing machines, the principal object of the invention being to provide a device of this ,character in which the spray tubes can.

proceeds, the invention consists in the novelfeatures of construction and combination of parts which will be more fully descr bed hereinafter and particularly pointed out 1n the claims.

In the drawings accompanying and forming part of this specification,

Figure l is a plan view of a. manifold.

embodying the present invention, the side walls of the enclosing casing being shown in section and broken away at them ends Fig. 2 is a broken-away, sectional view, on an enlarged scale, takenon the line 22 of Fig. 1; and, v

Fig. 3 is a sectional view taken approximately on the line 33 of Fig. 2.

The same characters of reference designate the same parts in the different figures of the drawings.

In the art of dish-washing machines, a device known as a manifold is generally employed for supplying a spray of water or. other cleansing fluid to the articles supported in the machine. The present invention relates only to this portion of the machine, and therefore it has been deemed unnecessary to illustrate the machine itself.

Referring to the drawings, 2. designates the side walls of the casing of the machine. Supported in one of the side walls is a tubular manifold 3, which is adapted to be connected at the exterior of the casing with a stand-pipe or other system of water supply. The manifold passes into the casing and extends transversely thereof, the free end being covered by asuitablecap 4-forming a; water-tight joint between; it and the manifold. y

"Extending from the manifold and in coin munication therewith are a plurality of spray tubes ornozzles 5, each of which is sealed at its free end by a plug Sand is provided. atone side with a longitudinally extending series of small perforations- 7 through which the cleansing fluid issprayed on the dishes to be washed.

It has been found extremely desirable in devices ofthis character that the spray tubes be removab-ly connected with the manifold for permitting said tubes to be properly cleaned. In all of the manifolds,

heretofore in use with which I am familiar,

the only way of detachably connecting the spray tubes with the manifold was by means of screw threads, but owingto'the length of time it took to removethem it I was seldom done, and consequently the tubes Very soon became foul and clogged, so that they did not perform their function efficiently. The present invention is intended to overcome this defect and to make the tubes so easily removable that the entire set canbe removed and, replaced after; each cleaning-operation, the" time consumed in removing and replacing the tubes being but avert v small fraction of that heretofore required. y

In theexample shown in the drawings,the manifold is provided with openings, one for each spray tube, the walls of said openings being beveled to form seats for the ends of the spray tubes or nozzles, which are correspondingly beveled, as shown at 8, Fig. 2. The spray tubes and their corresponding openings are ground to a nice fit so as to form a Water-tight joint when the nozzles are in operative position. nozzles in horizontal alignment with the manifold, I have provided a member 9 extending transversely of the casing andsecured thereto at. its opposite ends by means of brackets 10. This supporting member is preferably of L-shape in cross-section and the plugs fiat the ends of the nozzles are each formed with a tongue 11 which rests upon the horizontal leaf of the member 9, while the end of the plug abuts against the Vertical edge of said leaf. Spring members 12, one

For supporting the I for each nozzle, preferably bent into the form of loops, are secured to the vertical leaf of the member 9, each in proper position to engage the end of the tongue 11 of one of the nozzle and press the nozzle towards its seat in the manifold. By reason of this construction, the nozzles will have a swinging movement about the openings in the manifold, a vertically extending stop pin 13 being secured in the horizontal leaf of the member 9 for limiting the movement of each of the nozzles.

From theforegoing it will be seen that whe it is desired to remove the nozzles, it is necessary for the operator merely to grasp each nozzle in succession and swing its free end away from the pin 13 and beyond the influence of the spring 12, whereupon the nozzle can be readily removed from its opening in the'manifold. After the nozzles have been cleaned, they are replaced by seating their ground ends in the openings in the manifold and pushing their free ends over the horizontal leaf of the member 9 until they abut against the stop pins 13, as shown in the drawings.

While I have described in detail the de-' vice herein illustrated, it is to be understood that I do not thereby limit my invention to the precise features of construction shown, as I am aware that many mechanical changes and modifications may be made therein with out departing from the spirit'and scope of the invention as set forth in the claims hereto appended.

Having thus described my invention, what I claim is:

1. A device of the class described, comprising a supply pipe, a plurality of spray tubes each having one end in communication with said pipe transversely thereof, and means acting on the opposite ends of the tubes for maintaining the same in contact with the p A device of the class described, comprising a supply pipe having an opening in its side wall, the wall of said opening being :1

adapted to form a seat, a tube having one end adapted to be seated in said opening to form a liquid-tight joint, and means acting on the opposite end of the tube for retaining thereof, means for supporting said tube in horizontal alignment with the pipe, and

flexible means exerting pressure on said tube c in the direction of its axis thereby to retain the tube in close contact with the pipe.

5. A device of the class described comprising a pipe, a tube having one end in communication with said pipe transversely there'- of and adapted to be swung relative thereto, and means acting on the opposite end of said tube for maintaining said tube in horizontal alignment in contact with said pipe.

6. A device of the class described, com

prising a pipe, a tube having one end in communication with said pipe and adapted to be swung relative thereto, flexible means I for exerting pressure on the opposite end of the tube thereby to retain the same in contact with said pipe, and means for limitin the swinging movement of the tube in one c irection.

In testimony whereof 'I have signed my name to this specification.
